Abstract
Abstract A coil assembly comprising an electrically insulating support, a coil winding mounted on the support, and first and second terminal members. The support includes a main portion, a flanged portion extending from the main portion, and first and second terminal receiving sections extending from the lower periphery of the flanged portion for receiving the respective first and second terminal members. The flanged portion has a first surface contiguous with the main portion, a second surface opposite the first surface, an opening extending between the first and second surfaces, and a slot within the second surface extending from a point adjacent the first terminal receiving section to the opening in the flanged portion at a point adjacent the main portion. A start wire portion of the coil winding extends from the first terminal member, within the slot in the second surface and through the opening in the flanged portion to the main portion at a point adjacent the beginning of the first turn of the coil winding. A terminating wire portion of the coil winding extends from the end of the last turn of the coil winding to the second terminal member. The coil winding is containable within a conventional molded plastic encapsulating material.

Total Claims: 5
Claim 1
Independent Claim
339 words
An encapsulated coil assembly comprising: a. an electrically insulative support including a main portion, a flanged portion extending from said main portion, and first and second terminal receiving sections, said flanged portion comprising top, bottom and first and second side sections having a first surface contiguous with said main portion and a second surface opposite said first surface, said first side section having an opening extending between said first and second surfaces and a slot within said second surface, the slot extending from said bottom section at a point adjacent said first terminal receiving section to the opening in said main portion, each of said first and second terminal receiving sections extending from said bottom section and having a channel extending completely therethrough in a direction from the top section to the bottom section of said flanged portion; b. first and second terminal members positioned within said first and second terminal receiving sections respectively; c. a coil winding surrounding said main portion, said winding including a first turn, a last turn, a start wire portion and a terminating wire portion, said start wire portion extending from said first terminal, through the channel in said first terminal receiving section to within the slot in the second surface of said flanged portion, then through the opening in said flanged portion to said main portion and the beginning of said first turn of said coil winding, said terminating wire portion extending from the end of said last turn of coil winding to said second terminal member; and d. encapsulating material surrounding said coil and said support, whereby during the encapsulation of said coil assembly, and while said encapsulating material is flowing in the direction from said top section toward said bottom section of said flanged portion and through the channel in said first terminal receiving section, sufficient pressure is applied to said start wire to insure firm placement of said start wire within the slot in the second surface of said flanged portion after completion of the encapsulation of said coil assembly.
Claim 2
Dependent Claim
339 words
An encapsulated coil assembly comprising: a. an electrically insulative support including a main portion, a flanged portion extending from said main portion, and first and second terminal receiving sections, said flanged portion comprising top, bottom and first and second side sections having a first surface contiguous with said main portion and a second surface opposite said first surface, said first side section having an opening extending between said first and second surfaces and a slot within said second surface, the slot extending from said bottom section at a point adjacent said first terminal receiving section to the opening in said main portion, each of said first and second terminal receiving sections extending from said bottom section and having a channel extending completely therethrough in a direction from the top section to the bottom section of said flanged portion; b. first and second terminal members positioned within said first and second terminal receiving sections respectively; c. a coil winding surrounding said main portion, said winding including a first turn, a last turn, a start wire portion and a terminating wire portion, said start wire portion extending from said first terminal, through the channel in said first terminal receiving section to within the slot in the second surface of said flanged portion, then through the opening in said flanged portion to said main portion and the beginning of said first turn of said coil winding, said terminating wire portion extending from the end of said last turn of coil winding to said second terminal member; and d. encapsulating material surrounding said coil and said support, whereby during the encapsulation of said coil assembly, and while said encapsulating material is flowing in the direction from said top section toward said bottom section of said flanged portion and through the channel in said first terminal receiving section, sufficient pressure is applied to said start wire to insure firm placement of said start wire within the slot in the second surface of said flanged portion after completion of the encapsulation of said coil assembly.
Claim 3
Dependent Claim
49 words
A coil assembly according to claim 1, wherein each of said first and second terminal members has a major section, a pair of cantilevered fingers extending at approximately right angles from said major section, and a pronged section extending from the juncture of said fingers and said major section.
Claim 4
Dependent Claim
32 words
A coil assembly according to claim 2, wherein the channels of said first and second terminal receiving sections are slotted to receive said fingers of said first and second terminal members respectively.
Claim 5
Dependent Claim
35 words
A coil assembly according to claim 2, wherein said start wire portion and said terminating wire portion are fixed between said pronged section and said major section of said first and second terminal members, respectvely.
